Do you have any plans to develop Direct Sales Advertising plugin?

I'm currently using adspeed.com, I am wondering if you plan on developing a plugin that would allow for the direct sale of banner advertising to sponsors instead of having to go through a third party? Important Specs: Ability for sponsors to upload banners within parameters for ad zone, change banners at any time during their campaign, view performance stats, independent verification of their stats, payment processing, order held in moderation until accepted by site admin, prices set by duration, clicks and views with ability to set discounts according to volume. Others: video ad uploads, interstatial option.
